devices of that class available for' enhancing the vaporization of the power medium or .fluid inflowing to the interior of the cylinder' orcylindcrs of a so-ei'illed hydro-carbon oi-"explosive engine. and essentially to facilitate the .startingandjncrease the otherwise I h j' devices being we l 'tlesl a fviipbi'ifiing attaelunents for explosive engines. v

The object. of this invention is to provide a'vaperizingatltachinent of the character 'ttfOM-iltld which shall be simple andi'iiexpcnsiyo asl regards'its construction; durable, etficieat aha reliable in practical service;-;oonvenient in its ap ilication to practical purposes; and which s ali poms-a certain well-defined advantages over .prior analogous constructions.

A The iityention consists in the combinations. details and parts whereby. together with the novel-disposition and relative a r rangeinent of --1id parts, the tltttllllllltdlt of the foregoing object is rendered practicable, all of which will be hereinafter more specifically referred to and set forth in the claims hereto appended.

The invention is clearly illustrated in the aecoinpanyi ng drawing. wherein F igure 1 is a side elevation of a vaporiz ing attachment for -exph-iaiviengines llllbodying iu v saidiinproveiiients. an explosive engine being shown'also in' side elevation conjunetively therewith. to better illusl rate the practical application of the device.

Having reference to the accompanying drawing, wherein similar referenee-cliaracters denote like parts throughout the several views, and wherein, to facilitatethe desoripthat of mi" inipmved-vaporizin attachment in its application to a so-called, iydro-carbon or explosive; c t-Ii ureter, I, -in'. carrying out my present invention. make use of a joint-block 2, having a central power-mixture assage 2',said jflll'lir-llltlt'k bemg pierced, radially by preference, for the formation of a stopper-rceeiving opening 2": at a suitable point or segment thereof circumferentiallly of the passage and intersecting and communicating therewith. and preferablyfor the formation of a similar opening 3, at that point or segment of thejoint-block situated diametrically opposite the opcning-Q and aliiiing'axiallv therewith, the opening 3' heing duly threaded interiorly for the reception of zysuitable exteriorly threaded plug 3', which serves as a closure for the opening 3, and which may be readily dis- )lilt'ttl for facilitating the cleansing, if needlllhilf the interim-of the joint-block aforellamttlutljt'. latter constituting a segment of the llnid feed-conduit made use of. and being situated. in this instance, intcruiediato the carhureter outlet, 3'-', fitted with an annular flange 4 and the -nianifold intake 4'. having an annular flange .4"-. andheing there lirn-ly held. as through the. medium of thelmlts :"i. piercing the flanges 4, 4", respectively. with .the, joint-block aforenained positioned therehetween, and fitted,

rcsm-ctivcly. at their threaded advance ends 165 ,with suitable fasten-mg nuts 5",

5", whereby the adjoining parts may bedrawn snugly together, all as clearly illustrated in the tlt'rmltlmlt \'lllg drawing.

The opening 2" is formed taperingfrom its mouth inwardly. to the end that a suitable stopper, having a correspondingtaper,

.ofid d ii-rgenerally such engine, B'its nianifold and C its' car- 75 ma be snugly seated therein and serve as a closure therefor.

In this connection, and to better encompass the purposes of my present invention, I contemplate providing a plurality of stoppers 6 6', correspondingly tapered and adapted to be interchangeably availed of as closures'for the opening 2", the same being suitably tapered, respectively, to this end, and each, accordingly, being a counterpart of the other as re ards its tapered form and, hence, its adapts. ility to serve as a closure for said opening.

The stopper 6 is preferably provided with an eye 6", to facilitate the attachment thereof to any suitable object, as the lug T, and as through the medium of a suitable flexible connection, as the chain 7', whereby misplacement of the stop r now under considcration is obviated, ug 'i',' being, by preference', provided with'a suitable hole 7 to receive and retain said stopper when not in use.

Stopper 6 isfurtlier provided near its diametrlcally enlw nd nith a lateral airintakexport w'p: fliicli 'lcads'inivardly -,a1i"--initial air-inlet t' terminatingat and in communication with an 'interniediate'cens tral, longitudinal airsinlet 8, of a given diameter, mid jaii'einlet B in turn terminating at and in coniiiiuiiicationjwitli a final airinlct 8?,"thc. latter beingidiametrically enlar to' form' avalve-seatB", towluch is yic dinglyand snugly held, under normal conditions, and as through the medium of a spiral spri 8'", a cuprvalve -9, said cupvalve recivi and'housin the adjacent and of the spnn g 8", and t s latter occupying' the finalalr-inlet 8' and abutting endwise at its opposite end against the radially inturned flange 9',-preferabl interrupted as shown, at the inner odd 0 the sto per 6, and bring dul confined, through tie medium of said ange, within theair-inlet 8', as will be clearly noted on reference to the drawing a The stopper 6' has a neral tapered form conforming, articular y, at its diametrically enlarged end-portion, tothat of the stopper 6, and to such an extent is a counter art of the latter. Stopper 6', however, is, y preference, more elongated than stolpper 6, and while bein a-counterpart of t 1e latter imits ada'ptabi ity to'serve as a closure for the opening 2", the same is formed solid as shown.

I'contem late providing stopper 6" with a suitable iand-pi ce 9", the latter being, by preference, pro Med with an eye 9" at its free end.

In practice, and for priming or starting purposes in connection with explosive engines of practically all types,- it is desirable and not merely essential in low atmospheric I temperatures, that the infiowing powermixine, and I accomplish this important end,. in en mes to which my improved vaporizer may e applied, by duly preheating, at any available source of heat, say, stopper 6', and thereafter inserting the same snugly into the opening 2", this more elongated, and incidentallysolid form of stopper, which then traverses diametrically the intake passage 2' and has a substantial, heat-radiating surface, diffuses its contained heat in a manner to markedly increase the temperature of the power-mixture. as the same approaches in volume and inflows from said stopper, there, by well preheating and hence va such infiow'ing power-mixture and acilitats ing the priming or starting of the engine accordingly.

The engine having been gotten well in rising motion in the manner above stated, stopper I 6, say, may now be interchanged for the sto r 6' and accordingly snugly seated wit h i: the opcning 2", to-thereserve' .bgthas a more 'permanent'closure for theo" "-1-. ing 2" and incidentally'las a controllii lc" auxiliary air-inlet to be shortlyhereinafter cxfl'plained; and in this conn ectiolfr, and av'hi'le a o rding materially 1cm heat-radiating 'su'r-' face, stopper 6 may beme tsur abl heated, as defined in conjunction 1w1tlistop- With the engine underway .as stated, it.

becomes nbt r'are-desirable, for speed-upand other eiiiciency-enhancing purposes, attainable through increased vaporization of the power-mixture inflowing from the carbureter C, that the power-mixture availed of be controllably surcharged with auxiliary "volumes of atmospheric air, and I attain this last-named cm by providing stopper 6, say, with a suitable general air-inlet such as formed by the in ercommunicating constituent air-inlets 6', 8, 8', having a lateral intake-port 7", the inflow of such auxiliary volumes of atmospheric air, by way of the 'neral air-inlet aforenamed, and into the intake-passage 2', for its surcharg'ing direct there on the infiowing p0 r-mixture, be-. ing automatically induced under the suction of the engine in o ration, cup-valve 9 bein .the'reunder cause to recede from its seat 8 against the tendency of the spring 8'", thus opening the general air-inlet aforenamed, and port 7" being open to the atmosphere.

3O well adapted Tov the end that theinflowing air may be definitelycontrolled fistmvolume, I provide a, shut-oil? I shoulder '1 V which maybeeflected oper distribution of the material of the oint-block 2, as clearly indicated in Figs. 5 and (lot the drawing; and in this connection, when stopper 6. say, occupies its position shown in Fig. 5, with its intake-port 7" out of registry with the shoulder 10, outside air is free to move in volume into the intake-opening 2. by way of the general air-inlet aforenamcd and its port 7, valve 9 being open, while such in-moving volume of air may be diminished or controlled by duly rotating the stopper last-nemed'on its own longitudi nal axis, and proportionally to the extent to which the port 7" may, through rotation of said stopper as stated, be brought into closing registry with the shoulder 10, as will be clearly understood.

\Vhen either of the stoppers at'orenamed is in service as a closure for the opening 2, the other, to obviate its misplacement, may conveniently occupy the hole 7' formed in i1 formation of he operation of my improved vaporizing attachment for explosive engines should be apparent from the foregoing description thereof; and it will be seen that the same is for the purposes for which it is intended. and further that the same may be modified to a considerable extent, particularly as regards the specific form of the heatable stopper for the opening i made use of, and other minor details of the general construction, without material departur from the spirit and principle of my invoi'rtion as coming within the scope of the claims hereto appended.
